One other cool reference site for colors. Has all the models from the very beginning, and photos of each bike in every color offered. Not sure how accurate it is, but I believe they're at least all the colors offered in America (which seem to be completely correct).

Re: Parts sources for our cb750s. Added some links to sources for info or parts 02-13-14

Here is a link to a parts site that I just found. http://www.allcyclesupply.com/ They have some really good prices, and better yet, they have lists of all the models a particular part will fit.
